(A) Reporting
source water monitoring results.
(1) Systems
shall report results from the
source water monitoring required by paragraphs
(A) to (H) of rule
3745-81-65 of the Administrative
Code no later than ten days after the end of the first month following the
month when the sample is collected.
(2) All systems serving at least ten thousand
people shall report the results from the initial
source water monitoring
required by paragraph (A) of rule
3745-81-65 of the Administrative
Code to the primacy agency at the time of this requirement electronically. If a
system is unable to report monitoring results electronically, the system may
use an alternative approach for reporting monitoring results that the primacy
agency approves.
(3) Systems
serving less than ten thousand people shall report results from the initial
source water monitoring required by paragraph (A) of rule
3745-81-65 of the Administrative
Code to the primacy agency at the time of this requirement.
(4) All systems shall report results from the
second round of
source water monitoring required by paragraph (B) of rule
3745-81-65 of the Administrative
Code to the
director.
(5) Systems
shall report the following applicable information for the
source water
monitoring required by paragraphs (A) to (H) of rule
3745-81-65 of the Administrative
Code:
(a) Systems shall report the following
information for each Cryptosporidium analysis:
Public water system (PWS) ID;
Source treatment unit (STU) ID;
Sample collection date;
Sample type (field or matrix spike);
Sample volume filtered (L), to nearest 0.25 L;
Was one hundred per cent of filtered volume examined;
and
Number of oocysts counted.
For matrix spike samples, systems shall also report the sample
volume spiked and estimated number of oocysts spiked. These data are not
required for field samples.
For samples in which less than ten liters is filtered or less
than one hundred per cent of the sample volume is examined, systems shall also
report the number of filters used and the packed pellet volume.
For samples in which less than one hundred per cent of sample
volume is examined, systems shall also report the volume of resuspended
concentrate and volume of this re-suspension processed through immunomagnetic
separation.
(b) Systems
shall report the following information for each E. coli analysis:
PWS ID;
STU ID;
Sample collection date;
Analytical method number;
Method type;
Source type (e.g., flowing stream, lake/reservoir, well
designated as surface water);
E. coli/one hundred milliliters;
Turbidity. (Systems serving less than ten thousand people that
are not required to monitor for turbidity in accordance with paragraphs (A) to
(H) of rule
3745-81-65 of the Administrative
Code are not required to report turbidity with their E. coli results.)
(B)
Grandfathering previously collected data.
Systems may comply with the initial source water monitoring
requirements of paragraph (A) of rule
3745-81-65 of the Administrative
Code by grandfathering sample results collected before the system is required
to begin monitoring (i.e., previously collected data). To be grandfathered, the
sample results and analysis shall meet the following criteria and shall be
accepted by the primacy agency at the time of this requirement:
(1) A system may grandfather Cryptosporidium
samples to meet the requirements of paragraph (A) of rule
3745-81-65 of the Administrative
Code when the system does not have corresponding E. coli and turbidity samples.
A system that grandfathers Cryptosporidium samples without E. coli and
turbidity samples is not required to collect E. coli and turbidity samples when
the system completes the requirements for Cryptosporidium monitoring in
accordance with paragraph (A) of rule
3745-81-65 of the Administrative
Code.
(2)
E. coli sample analysis. The analysis of E. coli samples shall
meet the analytical method and approved laboratory requirements of paragraphs
(H) to (J) of rule
3745-81-27 and rule
3745-89-11 of the Administrative
Code.
(3) Cryptosporidium
sample analysis. The analysis of Cryptosporidium samples shall meet the
following criteria:
(a) Laboratories analyzed
Cryptosporidium samples using one of the following analytical methods:
(i) USEPA method 1623, "Cryptosporidium and
Giardia in Water by Filtration/IMS/FA" United States environmental protection
agency, 2005, EPA-815-R-05-002.
(ii) USEPA method 1622, "Cryptosporidium in
Water by Filtration/ IMS/FA" United States environmental protection agency,
2005, EPA-815-R-05-001.
(iii) USEPA
method 1623, "Cryptosporidium and Giardia in Water by Filtration/IMS/FA" United
States environmental protection agency, 2001, EPA-821-R-01-025.
(iv) USEPA method 1622, "Cryptosporidium in
Water by Filtration/ IMS/FA" United States environmental protection agency,
2001, EPA-821-R-01-026.
(v) USEPA
method 1623, "Cryptosporidium and Giardia in Water by Filtration/IMS/FA" United
States environmental protection agency, 1999, EPA-821-R-99-006.
(vi) USEPA method 1622, "Cryptosporidium in
Water by Filtration/ IMS/FA" United States environmental protection agency,
1999, EPA-821-R-99-001.
(b) For each Cryptosporidium sample, the
laboratory analyzed at least ten liters of sample or at least two milliliters
of packed pellet or as much volume as could be filtered by two filters that
U.S. EPA approved for the methods listed in paragraph (B)(3)(a) of this
rule.
(4) Sampling
location. The sampling location shall meet the conditions of paragraph (J) of
rule
3745-81-65 of the Administrative
Code.
(5) Sampling frequency.
Cryptosporidium samples were collected no less frequently than each calendar
month on a regular schedule, beginning no earlier than January 1999. Sample
collection intervals may vary for the conditions specified in paragraphs
(I)(2)(a) and (I)(2)(b) of rule
3745-81-65 of the Administrative
Code if the system provides documentation of the condition when reporting
monitoring results.
(a) The primacy agency at
the time of this requirement may accept grandfathering of previously collected
data where there are time gaps in the sampling frequency if the system conducts
additional monitoring the primacy agency specifies to ensure that the data used
to comply with the initial
source water monitoring requirements of paragraph
(A) of rule
3745-81-65 of the Administrative
Code are seasonally representative and unbiased.
(b) Systems may grandfather previously
collected data where the sampling frequency within each month varied. If the
Cryptosporidium sampling frequency varied, systems shall follow the monthly
averaging procedure in paragraph (A)(5) of rule
3745-81-67 of the Administrative
Code, as applicable, when calculating the bin classification for
systems.
(6) Reporting
monitoring results for grandfathering. Systems that request to grandfather
previously collected monitoring results shall report the following information
by the applicable dates listed in this paragraph. Systems shall report this
information to the primacy agency at the time of this requirement.
(a) Systems shall report that they intend to
submit previously collected monitoring results for grandfathering. This report
shall specify the number of previously collected results the system will
submit, the dates of the first and last sample, and whether a system will
conduct additional
source water monitoring to meet the requirements of
paragraph (A) of rule
3745-81-65 of the Administrative
Code. Systems shall report this information no later than the date the sampling
schedule is required by paragraph (I) of rule
3745-81-65 of the Administrative
Code.
(b) No later than two months
after the applicable date listed in paragraph (C) of rule
3745-81-65 of the Administrative
Code, systems shall report previously collected monitoring results for
grandfathering, along with the following associated documentation:
(i) For each sample result, systems shall
report the applicable information in paragraph (A) of this rule.
(ii) Systems shall certify that the reported
monitoring results include all results the system generated during the time
period beginning with the first report result and ending with the final
reported result. This applies to samples that were collected from the sampling
location specified for
source water monitoring in rule
3745-81-65 of the Administrative
Code, not spiked, and analyzed using the laboratory's routine process for the
analytical methods listed in paragraph (B)(3)(a) of this rule.
(iii) Systems shall certify that the samples
were representative of a plant's source water and the source water have not
changed. Systems shall report a description of the sampling locations, which
shall address the position of the sampling location in relation to the systems
water source and treatment processes, including points of chemical addition and
filter backwash recycle.
(iv) For
Cryptosporidium samples, the laboratory or laboratories that analyzed the
samples shall provide a letter certifying that the quality control criteria
specified in the methods listed in paragraph (B)(3) (a) of this rule were met
for each sample batch associated with the reported results. Alternatively, the
laboratory may provide bench sheets and sample examination report forms for
each field, matrix spike, "Initial Precision and Recovery (IPR)", "Ongoing
Precision and Recovery (OPR)," and method blank sample associated with the
reported results.
(7) If the
director determines that a
previously collected data set submitted for grandfathering was generated during
source water conditions that were not normal for the system, such as a drought,
the
director may determine not to accept the data. Alternatively, the primacy
agency may accept the previously collected data if the system reports
additional
source water monitoring data, as determined by the primacy agency,
to ensure that the data set used under paragraphs (A) to (D) of rule
3745-81-67 of the Administrative
Code represents average
source water conditions for the system.
(8) If a system submits previously collected
data that fully meet the number of samples required for initial
source water
monitoring in accordance with paragraph (A) of rule
3745-81-65 of the Administrative
Code and some of the data are rejected due to not meeting the requirements of
this rule, systems shall conduct additional monitoring to replace rejected data
on a schedule the primacy agency at the time of this requirement accepts.
Systems are not required to begin this additional monitoring until two months
after notification that data have been rejected and additional monitoring is
necessary.
